T0 all whomI it may concern l 1 Be it knownthat I, CHARLES W. GASTO, a citizen of the United States of America, Aresiding, at VashiDgtOn, in the county of Washington and State of Pennsylvania, have invented certain new `and useful Improvenients in Box-Flap Gluing aiid Sealing hereinafter set forth, for adjusting the machine to provide' for diffe-rent size of paper boxes and cartons.

Further objects ofthe invention are to" provide a machine for the purpose set forth which is simple in its construction andarrangement, strong, durable, eliicient and convenient .in its use, readily set up and comparatively inexpensive to manufacture.

With the foregoing and other objects inview, the invention consists ofthe novel construction, combination and arrangement of parts as hereinafter more specifically described and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modiications 'can be resorted to which come within'the 'scope of the claims hereunto appended.

In the drawings wherein like reference characters denotei correspondingl parts' throughout tthe several viewsr-Figure 1 is a top planview ofa. machine in accordance with this invention, Fig. 2 is a side elevation,

Fig. 3 is a perspective view, broken away,`

Fig. 4 is a transverse section, Fig. 5 is a detail illustrating ythe conveyer, and Fig. 6 is a detail.-

Referring to the drawings indetail, 6 and 7 denote a pair yof supporting members, the former having a IV-shaped groove 8 in its upper face and the latter having a V-sliaped groove 9 in its upper face. Extending parallel 'to the member 7 and spaced therefrom as well as being ofA less length than the meniber 7, is a supporting membery 10 provided with a V-shaped grooye 11 in` its Iupper face.

The inenibersvG, 7 and 10 are connected together by a longitudinally extending bar 13 and the members 6 and 7 are connected to`- gather by a longitudinally extending bar 14, which is of less length than the bar 13. The member 7 is connected to the member 10 by a longitudinal bar 15 and arranged parallel to the bar 15 is a longitudinal bar16, which is secured at one end to a slide 17 movable' in the groove 11. The other end of the bar 16 is connected to a slide 18, which travels in the groove 9. T he slide 18 is connected by a 'bar 19 to a slide traveling in the recess 8.

Projecting from each end of the bar 13 are bearings 21and 22 andV journaled in and projecting from the bearing 31 is a. threaded shaft 23, which has its threads engaging with the threads of an interiorly threaded sleeve 24 carried by the slide 17. The 'shaft 23 ycarries a beveled gear 24a, which meshes with the beveled gear 25 carried by a countershaft 26, which is journaled at one end in a. bearing 27, the latter projectiiig from the bar 13. -The countershaft 26 is also journaled in a bearing 28 which projects from the b'ar 13 and said counter; sha-ft has a beveled gear 29 which meshes with the beveled gear 30 carried by a shaft 31, the latter being journaled in the bearing 22.. The shaft 31 in its outer end is provided with a hand wheel 32 and is provided at its inner end with threads` 'which engage with the threads of an interiorly threaded sleeve 33 carried by the slide 20. The slide 18 provides what may be termed a \coupling means between the bars 16 and 19 so that said bars will be adjusted in unison. The adjusting of the bars 19 and 16is had through the medium ofthe shaft 31, which when revolved by the hand wheel 32 will impart a like motion to the shaft 23 and as the threads of the shaft 23 and 31 engage with the threads of the collars 34 and 33, it is obvious that the bars 16 and .19 will be adjusted and in a direction depending on the direction in which the hand wheel 32 is revolved# .j

Journaled in the bars 15 and 16v are the shafts34 of'a'series of transversely eXtendf ing rollers 35. The shafts 34 project from .the bar 16 a suliicient distance so that when by the bars 15 and 16.

Secured to the slide 18 is a vertically disi posedupright 36, secured to `the bar and' opposingV the upright 36 is a verticallydisposed upright 37 and sec-ured to the rear u ends of the bars 15 and*16 is an upright` 38 scribed, the description of one lapplying tothe other. The member 39 aswell 'as the member 40, is provided withy a serles ofl bearings 41 and a series of integral` frames 42 between 'each pair of which is arranged a bearing 41. Arranged in each of the frames 42 is a vertically adjustable bearing 43 which is provided with an adjusting screw 44, the latter extending through the top of the frame and formed witha worm gear 45. i 5 Journaled in the barsv 15 and 16 and 'in the bearings 41 are the shafts 46 ofpvertically disposed rollers 47 and journaled inthe bearings 43 are shafts 48 of transversely extending rollers 49, which are arranged parallel to the rollers 45. The shafts 48 project outwardly from the member 39 so that' when the 'bar 16 is adjusted outwardly, theshafts 48 will be supported yas the member 39 is moved in unison with the bar 16. .The uprights 36, 37 and 38 are provided with a vertically- 'disposed support 50, having a bearing 51 at'the upper end and journaled in the bearings 51 are longitudinally extend- L ing shaftsA 52 provided 'with worms .53,

which mesh with the worm gears 45. The

vshafts 52 have hand wheels 54 t'o` enable the convenient revolving of the .shafts 52wherey the worm gears will be revolved aild thebearings43 adjusted.

, Mounted upon the bars14 and 19 in proximity to each end'of said bars, is an u right 55, and each of lsaid uprights 55 is ormed with ,ai verticallydisposed pocket 56 having extendinginto the vmouth thereof an interiorly threaded iange sleeve 57. The flange of each of the sleeves 57 is indicated at 57; which engages the Atop edge 'of its respective upright 55. The Asleeve 57 'isfxedly securedj to its respective'upright 55.

Mounted Iupon the uprights .55 are longitudinal members 5 9 and 60 'and attached to said membersnear 'each end thereof. is the spe'et to each-.other and -in eachibearing 62 isarran cda. wcrmgear 64carried by a vertically isposed screw,-65r,l{.which extends' member 59 arid 60 and engages withthe threads of the sleeve, 57 and extends int'o are longitudinally extending shafts 65, each provided' ith aV pair of worm gears 66 which mesi;I with a pair of worm gears 64. Each of theshafts 65 is provided with a hand wheel 67. -By turning the wheel 67 the shaft 65 will revolve and as the worms 66'mesh with the 'worm ear 64, it is obvious that the screws 65a will be revolved and the members 59 and 60 be'elevated or lowered, depending upon the direction of movement of the screws 65, 'A

Journaled in the bars 14I and 19, are the 69. The spindles 68 project from one side to be supported whenJthe bar 19 is adjusted toward the member 13. Connected to the member 59 is a pair of inwardly extending transversely dlsposed of a longitudinally extending resilient bracing the boxes or cartons upon the rollers 69 as they are conveyed through that portion of the machine in which the iaps are provided with glue.

Arranged between the uprights 55 are box flap opening and closing members and which opening members of the pair consists of a pair of. longitudinally disposed oppositely extending inclined bars 72 and 73, the former inclining upwardly and the `latter d wnwardly. The forward ends of the said ars are inset asat 74 and pivotally connected together asat 75. The rear ends of said bars arel bent outwardly at right angles as at 76. \Tl 1e .rear end of the bars 72 are provided with anupright portion 78 which are fixedly secured to the members 59 and 60, as at 7 9. The rear ends .of the'bar 72 Vare bent downwardly as at 80 and are ixedly' secured to the bars 14 and 19 as at 81.' The flap closing members extend in an opposite direction `with respect to the flap opening members and a pair offlap closingl members is emsists. of'a pair'of bars 82' and 83, having their rear endspivotally connected as at 84. The bars 82l have their forward ends xedlysecured to the members 59`and 60 as at 85 and secured? to` the bars 14 and 19 as 'at 86. The bars 82 are of compound curvature and `incline,do 'wardly toward the rear end of the aehine'whilethe bars 83 are of comlpound curvature and -incline upwardly'toends of the bars 82 and: 83 arepositioned-inwardly. with -re'spect to the forward ends thereof-14.

through the bearing 62 of" its Arespective of the bar 19, and which enables the rollers supports having' attachedthereto the ends` .the bars 83 have their forward ends ixedly' ward the rea'rend of the-machine." The rear the pocket 56.' Journaled -in the bearing 63 spindles 68 of transversely extending rolls' ing element 71 for the purpose of maintainare arranged in pairs. Each of the ap 11.5 ployed and e'achjiap closing. member con- 15 being arranged over thefrollers 69 at one endl ed upon a base 92 which projects from the 7 3 together, the bars 82 and 83 together, itis 4 obvious that provision is made to allow of the adjusting of the members 59 and 60 upwardly and downwardly when occasionfso nrequires and furthermore itxprovides for the positioning ofthe forward ends of the flap openers and rear ends of the flap closers cen- -trally ofthat portion of the machine which is employed for applying'glue to, the flaps of the boxes or cartons. Connected to the bar '13 is a support 87 in which is arrangedl a-vertically adjustable arm 88 having an inwardly extending upper portion 89 and carrying a glue applying brush 90, the latter thereof. The arm 88 is maintained in its adjusted position by a set screw 91. *Mountbar 14 is a lvertically disposed support, 93, in whichis arranged a vertically adjustable arm 95 having an inwardly extending portion 95 carrying a'glue applying brush 96, the latter being arranged opposite the brush 90. The arm 94 is maintained in an adjusted position by a set screw 97. The reference characters 98 and -99 denote glue supply pipes having their outlet ends 100 thereof arranged over the brushes 90 and 96. Each off the supply pipes is provided with a cuto 101.

The rolls 69. as well as the rolls 35 are provided centrally with a peripheral groove 102, and cog teeth .103 within said groove. The reference .character 104l denotes lan endless belt which passes through the grpove 102 of the, rollers and engages the teeth 108 for revolving the rollers. The belt 104 is provided with lugs 105, which abut against the packets or cartons for conveying these latter through the machina The spindle 68, of the rollers 69 at the .front end of the machine is extended as at 'the rollers 69 and 35.A

It will be assumed that a box provided with aps has been fed tothe front end of the machine, -from a suitable conveying mechanism and'that the belt 104 is operating. The Hap openers are so positioned that they will engage and extend the Haps ofthe box so that as the box is conveyed through themachine theinner faces lof the naps will be carried overthe glue applying rollers and glue will be supplied to the inner face of the flaps. As the. box is fed to the machine through the medium of the belt 104 and lugs 105, the Haps will be moved against the body of the box and as the boxfis further engaged by the rollers 47 and lthe flaps will l be sealed against the body portion of the box. 'llhat portion ofrthe machine in-which is arranged the glue applying brushesis adjustable to provide for various sizes of cartons in view of the fact that the bar'19 and member() are laterally adjustable .and meinber vertically adjustable and that that portion of the machine in which is arranged the rollers 147 also has provisionL to provide for dilferentv size boxes owing to the fact `that the bar and member-89 are laterally adjustableand the member 39 vertically adjustable.
